10% raise
hmm
find his amount earned first
15.5 per hour
15.5 times 35=542.5
10% more is times 1.10
542.5 times 1.10=596.75
5% is deducted for tax
100-5=95
596.75 times 0.95=566.9125
now add 200
766.9125
round
$766.91 is his check
Answer:
x = -1.
Step-by-step explanation:
√(x + 10) - 4 = x
√(x + 10) = x + 4
Squaring both sides:
x + 10 = x^2 + 8x + 16
x^2 + 8x - x + 6 = 0
x^2 + 7x + 6 = 0
(x + 6)(x + 1) = 0
<u>x = -6, -1.</u>
Check for any extraneous roots:
√(x + 10) - 4 = x
<u>Try x = -6:</u>
√(-6 + 10) - 4 = 2 - 4 = -2.
but we found x = -6 , so -6 is not a root.
<u>Try x = -1</u>:
√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.

Answer:
The 1 represents a whole number, and 28/99= .28282828 (the repeating decimal wanted)
Therefore 1.28= 1 28/99
